Hi, https://pointfree.io/ gives: Input: f x y z = x <> " " <> y <> " " <> z Output: f = ((<>) .) . flip flip " " . ((<>) .) . (<>) . (<> " ") So no, it's not something simple! For clarity I would recommend using the non-point-free version, even in the case given in the book. Use point-free only in simple cases like `map (+ 1)` where the meaning is obvious.

After a little playing with it... it seems to make sense. So I thought I'd try evolving from salutation and name to salutation, first, and last names. But, after a bit of tinkering, I haven't been able to make it work...
I'm sure it's something simple (one way or the other)... any help would be appreciated!
